8K receiver video fix: Do this if you own a Yamaha, Denon or Marantz
The Yamaha RX-V6A is affected by a 4K/120Hz video bug when used with certain devices.

Recent 8K-compatible AV?receivers from Yamaha, Denon and Marantz will need additional hardware fixes for a bug preventing them from displaying highest-quality video. Currently these models are unable to display video with a 4K resolution and 120Hz frame rate.?
Yamaha has announced that owners of its early 8K receivers, including the?V6A, will need to replace an internal HDMI mainboard if they plan on connecting an?Xbox Series X?or Nvidia RTX 30-series graphics card. Yamaha says that PlayStation 5 video playback isn’t an issue (unlike for Denon, see below). Yamaha says that affected users should register their devices and the company will advise customers of the next steps here in summer.?
Meanwhile, owners of new 2020 and 2021?8K-compatible Marantz and?Denon receivers?can request a free hardware dongle that’s designed to fix problems with?4K/120Hz?video playback. Denon’s external SPK618 HDMI adapter remedies compatibility problems with the?PS5,?Xbox Series?gaming consoles and graphics cards. Denon users can?sign up for the adapter here?and?Marantz owners can sign up here.?
Another workaround for owners of all of the below models is to connect the gaming console directly to the compatible TV and then use?HDMI eARC?to feed the receiver.?
Affected 8K-compatible receivers
| Brand | Model numbers |
|---|---|
| Denon | AVR-A110, AVR-X4700H, AVR-X3700H, AVR-X2700H, AVR-S960H |
| Marantz | SR8015, SR7015, SR6015, SR5015, NR1711 |
| Yamaha | RX-V4A, RX-V6A, RX-A2A, TSR-70 |
Most?4K TVs?and receivers are able to handle signals at 60Hz but the latest sources can offer 120Hz for smoother motion. However, gamers would encounter a black screen when connecting these sources to a TV via these receivers at 4K/120Hz.?According to one report, the problem is a result of a Panasonic-sourced chipset used for the 8K video sections in affected receiver models.?
None of the companies has yet advised when the on-sale models will be fixed, especially in the case of Yamaha, and so we would advise holding off on buying one of these receivers for now.
Denon’s SPK618 HDMI adapter is designed to fix 4K/120Hz compatibility issues.
